A Brief History

The project entails repairing the building at 335 Maplewood Ave in a manner that meets both preservation and sustainability goals. The building is the new location for Petersen Engineering, a firm that has been located in Portsmouth since 1992, and specializes in sustainable building engineering. We intend for this project to showcase techniques & materials that promote both preservation and sustainability and intend to share all aspects of the project locally and regionally through open houses, presentations, industry tradeshows, case studies and publications. We foresee this project being a valuable educational tool to demonstrate that preservation goals need not be compromised by sustainability goals. We have teamed with Bruss Construction who we know from past collaborations has exceptional experience and expertise on projects with the dual goal of preservation and sustainability.

The project received approval by the Historic District Commission on January 6, 2010 with construction scheduled to begin early February 2010.

The projected peak heat loss reduction is 85%.

Sills are in rough shape. Now what?

The sills are in pretty rough shape throughout the building. (See yesterday’s video for an example if you haven't already.) The Bruss Crew opened up the bottom 2' of the exterior walls for a good clear view of what is going on. Michael Bruss, Pete Swislosky & Dave King from Bruss Construction showed up this morning bright and early to evaluate the damage and come up with a plan. It turns out that each sill has a unique set of constraints. One solution is not going to work all the way around the building. Most sills need complete replacement. Some sections of foundation need to be repaired to support the new sills. The foundation repair is the big question for the moment. It is looking like we will be using built up pressure treated lumber to replace the damaged sills. I will share any further developments as they become available.
